This is a suspected variable star with an apparent magnitude that may rise as high as 2.76. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Beta Crucis, also called Mimosa or Becrux, second brightest star (after Alpha Crucis) in the southern constellation Crux (the Southern Cross) and the 20th brightest star in the sky. You can decline to give a name which if that is the case, the comment will be attributed to a random star.

Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet. But brightness does not necessarily mean unimportance, as testified by Hercules, one of the oldest and best known constellations in the sky even though its brightest [15], At Palomar Observatory, Antoine Labeyrie and others used speckle interferometry with the Hale Telescope to resolve the system in 1977. The star itself can be located at what could be said is the ankle of Hercules right leg. The Hipparcos satellite observed the orbital motion of the primary relative to other stars, and an orbit was computed in 2005 using spectroscopic data together with these measurements.

To give idea of size, the Sun is 99.86% the mass of the solar system. Corncorde before it was retired was the fastest commercial airline across the Atlantic and only one that could do Mach 2. It has a mass nearly three times the mass of the Sun, and has expanded to 17 times the Sun's radius. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. which to calculate using this website is too large. Gamma Herculis, which has no proper name, is one of those stars that graphically illustrates that Johannes Bayer did NOT always go by apparent brightness when in the early seventeenth century he applied Greek letters.
